Whether the diamond ring for a total solar eclipse comes out of the upper left or upper right corner

--The diamond ring of the total solar eclipse on July 22, 2009 came out of the upper right corner!

Both the Bailey Bead and the Diamond Ring occur just before and just after the eclipse, so both east and west can be formed, both by sunlight filtering through the gaps in the rugged peaks at the edge of the moon's silhouette when the moon is almost completely obscured from the sun. Before the eclipse, the "diamond ring" appeared earlier and longer than the "Bailey bead", which was formed by the diffraction of light from the exposed more solar circle and excessive **. At this point, a ring of light formed by the outer atmosphere around the Sun outside the black Moon can be seen.

As the sunlight is more blocked, the "diamond" gradually breaks into a string of pearl-like particles (two or three or even six or seven), which is called Bailey beads. Bailey beads last for a short time, usually only 1 3 seconds, and will soon disappear as the moon is more occluded. The process before the birth of light is the opposite, and the appearance of the first Bailey bead after the eclipse can be used as a sign of the moment of life.

Here's the whole process.

Hehe1 I didn't see it. Beijing does not! ~

It is from yesterday that it disappears in the lower right corner, and the sun begins to round.

Every place is different.

This is a complex question that requires two factors to consider.

Yes, the diamond ring will appear twice, and on the top of the total eclipse zone, the direction will be different depending on the position.

The first time is the time of eating, and the second time is the time of giving birth.

The first factor to consider is the direction in which the shadow of the moon moves, which is related to the direction in which the final vanishing ray of light is.

North of the centerline of the total eclipse zone, the moon shadow moves from top left to bottom right (to southwest to northeast).

Above the center line of the total eclipse zone, the Moon shadow moves from due left to right (to west to east).

South of the centerline of the total eclipse zone, the moon shadow moves from top right to bottom left, (to northwest to southeast).

The reason for the different directions is that the Moon Shadow is circular and the front border of the shadow is semicircular.

The second factor to consider is the reason for the formation of the diamond ring, the topography of the lunar surface.

For example, the last line of light to disappear is in the upper left direction, and where the gap between the peaks is the largest, the light comes through, which is the diamond ring we see. This factor, combined with the first factor, determines the final position of the diamond ring.

Because the Moon is always facing the Earth on the same side, the terrain around it is also fixed.

Looking at a large number of total solar eclipse diamond rings**, you can see that diamond rings appear in almost every direction, and sometimes even a string.

Then, we can basically judge based on the first factor.

I'm south of the center line, so the moon shadow moves from top right to bottom left, and the last line of light to disappear is on the bottom left, so the first time I see the diamond ring is on the bottom left, and the second time it's on the top right.

This is consistent with the situation in cities south of the center line that are broadcast live.

There is also Jiaxing just above the center line, so the first time is due right, and the second time is due left. There is **on the following one**.

Haha, I've been studying total solar eclipses for the past few days, and I've done a lot of research on moon shadows, and I can just answer your question.

In the case of the Diamond Ring, there are a lot of cities here.
